LEVI B. EBERLY, OF SMITI-IVILLE, OHIO.

BELT-AND-ROLLER PRESS.

SPECIFICATION forming part of Letters Patent No. 714,679, dated December 2, 1902.

' Application filed February 27, 1902. erial No. 96,008. (No model.)

To all whom it may concern:

Be it known that I, LEVI B. EBERLY, a citizen of the United States, residing at Smith ville, in the county of Wayne and State of Ohio, have invented certain new and useful Improvements in Belt-and-Roller Presses, of which the following is a specification.

The object of my invention is to extract liquids from solids when the latter are reduced to a granular, ground, pulverized, or pulpy state.

While my invention relates, primarily, to improvements in that class of machines known as belt-and-roller cider-mills, in which grinder and press are combined and operated simultaneously, it may be found equally useful used singly or in partial combination with other machines in desiccating many substances, such as salt, sugar, exhaust barley malt, commercial fertilizer, (X270.

With this end in view my invention consists in the novel construction, arrangement, and combination of parts hereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims.

Referring to the drawings, Figure 1 is a side elevation of the press, a portion of its side wall being broken away in order that the construction and arrangement of some of its parts may be more readily seen. Fig. 2 is a plan View, a portion of the endless carrier apron and one of the upper presser-rollers being broken away and the upper frame of rollers removed for a similar purpose. Fig. 3 is a transverse sectional View taken on line a b of Fig. 1. Fig. 4 is a detail view of the adjustable bearings for regulating the ten- Fig. 5 is a side elevation of a modification of the press. Fig. 6 is a sectional longitudinal View of the press.

Similar characters of reference indicate like parts throughout all the figures of the drawlngs.

1 designates the base-frame, to which the lower ends of the upright posts 2 are attached.

3 designates carrier-rollers mounted in suitable bearings attached to the frame of the press and over which moves an endless carrier-apron 4. For the purpose of adj usting the tension of the endless carrier-apron 4, to be made of foraminous material, a carrierroller 5 is mounted in adjustable bearings 6, (see Fig. 4,) carried by a boxing or frame 7, which is held in position by ways formed in the sides of the slot 8 of the supporting-frame, which frame 7 is adjustable by means of a thumb-screw or bolt 9. Behind the bearings 6 is interposed a piece of rubber 10 or a spring, if preferable, for the purpose of giving elasticity to the bearings 6.

11 designates a series of sets of presserrollers mounted in suitable bearings formed near the top of the upright posts 2.

For the purpose of regulating the pressure of the upper presser-rollers upon the lower ones the ends of the shafts of the upper presser-rollers are mounted in bearings 12, mounted in slots 13 and held in position by means of ways formed in the sides of said slots, (which will thus permit of a vertical movement of the bearings 12,) and the thumbscrews 14, the ends of which rest upon a piece of rubber 15, or a spring, if preferable, resting upon the bearings 12.

In orderto prevent an accumulation of ma terial before the presser-rollers 11 and hasten the flow of fluid through the carrier-apron 4, vacuum-boxes 16, covered with metallic screens, are placed immediately in front of said presser-rollers, over which passes the endless carrier-apron 4. These boxes are exhausted by means of a suitable pump L, and

the fluid thus pumped from the vacuumboXes is pumped and thrown in jets against the top side (or under, it preferable) of the returning endless carrier-apron 4 by means of pipes 17, provided with perforations or tubes 18, or by some other suitable and convenient device for throwing jets, for the purpose of removing and disengaging from the meshes of the endless carrier-apron any material or pulp that may have adhered to it.

Beneath the endless carrier-apron 4 and in front of the first vacuum-box 16 is mounted a series of rollers l9, mounted in suitable bearings of a frame 20, as shown in Fig. 3, attached to the insides of the upwardly-ere tending edge 21 of the walls or sides 22 of the press.

23 designates a frame containing and carrying a series of rollers 24, mounted in suitable bearings therein and pivotally attached at its rear end near the front set of presserless aprons 4 and 25.

rollers 11, as at b, to the upwardly-extending edge 21.

Passing around and covering the series of rollers 24 and carried by them is an endless apron 25, which receives its motion from the first upper presser-roller 11, around which it extends and revolves, transmitting power to the entire series of rollers 24 and moving in conjunction with the main endless carryingapron 4.

In order to provide for the adjustment of the endless apron 25, the last of the series of rollers 24 at the free end of the frame 23 is mounted, like carrier-roller 5, in an adjustable bearing 26 with thumb-screw. (See Fig. 4.) The endless apron 25 may be made pervious or impervious to fluid, as may be found most practical. sirable, the endless apron 25 need not pass over and receive its motion from the first upper presser-roller 11, as shown in Fig. 1, but may pass over the series of rollers 24 only, and any one or more of them may be provided with a suitable pulley and belting communicating with some other suitable source of power.

It will be seen that the rollers of the series of rollers 24 and19, unlike presser-rollers 11, do not bear or press directly against each other, but between each other, on the end- This is done for the purpose of hastening the flow or percolation of the fluid through the endless carrier-apron 4 and also to prepare and distribute the material or pulp for the action of the presserrollers 11,. hereinbefore described.

The free end of the frame 23 is attached, as at c, to the upwardly-extending edge 2]. by means of a spring-latch or some other suitable and convenient device, whereby the series of rollers 24 may be set at any desirable height from the endless carrier-apron 4, and the pressure of the same upon the endless carrier-apron 4 may be regulated under spring tension, so that if a large mass of pulp or material is passed between the endless aprons 4 and 25 the upper frame 23, carrying the series of rollers 24, will be caused to move oryield upwardly.

26 designates a substantially V-shaped adjustable spreader having its outwardly and rearwardly extending arms pivotally attached, as at d, to the upwardly-extending edge 21 of the side walls 22 of the press. It is disposed horizontally just above the endless carrier-apron 4, with its vertex just above the center of the same and extending forward and provided with an upwardly-extending springarm 27, having a series of openings adapted to take over a pin 28,attached to the wall of the press. p

29 designates forwardly and outwardlyextending arms attached to or integral with the.

rearwardly-extendingarms of the spreader 26 and designed to prevent the shoving of the material'or pulp to the margin of the carrierapron 4. The function of the adjustable Furthermore, if de spreader 26 is to evenly distribute the mate= rial or pulp on the carrier-apron 4, and being adj ustably attached, as at d and 28, it mayv material or pulp clinging to the endless aprons 4 and 25, there is mounted at the rear of the press arotary brush 30, mounted on a shaft and journaled in suitable bearings and provided with a pulley 31, to which motion is imparted by a belt 32, connected with a pulley 33, mounted on the shaft of the roller 3, and at the rear of the first presser-roller 11 there is adj ustably mounted on the edges of the upwardly-extending edge 21 of the walls 22 of the press a brush 34, which will brush from the endless apron 25 any material or pulp that may have adhered to it, and the material or pulp thus detached will fall upon the endless apron 4 and be carried through the succeeding presser-rollers 11. Brushes may be attached at any other suitable and convenient places, if found necessary or desirable, and any suitable means may be provided for regulating the pressure of the brushes on the endless aprons 4 and 25. 35 designates the upper tank, and 36 the lower tank, for containing the extracted fluid, and 37 designates the bottom of the upper tank. (See Fig. 3.)

As a further means of removing and disengaging from the meshes of the returning endless carrier-apr'on 4 any material or pulp that may have adhered to it it will be seen that I return the apron 4 through the fluid contained in the upper tank 35 near its bottom 37, and the same may be passed through a series of rollers K, similar to 19 and 24, hereinbefore described, or some other suitable-means for freeing its meshes of any material or pulp that may have adhered to it, and, furthermore,pany suitable and convenient device may be attached to said rollers whereby the same may be given a vertical motion and the carrier-apron 4 be thus agitated while passing through the same.

38 designates a filter box or drawer (shown in Fig. 3) designed to serve as a cover for the lower tank 36. This filter-box has a wire or metallic bottom and is covered with a suitable filtering-cloth 39, fastened to its sides and ends. It acts as a cover for the entire lower tank 36 and receives and filters the fluid from the upper tank. The fluid from the upper tank is conducted to the lower tank by means of pipes H, which carry the fluid from the openings I, in the side walls, to the lower tank, and is discharged through the openings J, just above the filtering-cloth 39.

The endless carrier-apron 4 has a cord or rope 40 in a hem in each margin which runs in an annular groove 41 near each end of the lower presser-rollers 11 and a groove 42 in the strips 43, over which the margin of the 'end of a shaft which extends through the feed hopper above the cylinder and has mounted thereon a feed-cylinder (not shown in drawings) which aids and regulates the feed to the grinding-cylinder below. Mounted on the same shaft or attached to the large pulley 46 is a sprocket-wheel 47, which transmits its motion'to a sprocket-wheel 48, mounted on one end. of the shaft of the carrier-roller 3, over which passes the endless carrier-apron 4. Upon the opposite end of the shaft of this carrier-roller dis mounted a sprocketwheel 49, which transmits its motion to the first set of presser-rollers 11 by means of a sprocket-chain 50, running thereon and over a sprocket-Wheel 51, mounted on the lower presser-roller 11.

From the first set of presserrollers 11 motion is transmitted in a similar manner to the remaining sets of presser-rollers 11 by means of sprocket-chains 52.

If found necessary or desirable, cog-wheels meshing with each other may be mounted on the ends of the shafts of the resser-rollers 11.

In the operation of the machine the material or pulp drops from the grinder upon the endless carrier-apron4 and is carried to the front end of the endless apron 25, traveling in the same direction, passing thereunder, and is subjected to thepressing action of the series of rollers 19 and 24, where a considerable portion of its fluid is extracted and forced through the meshes of the endless carrier-apron 4. After passing between therollers 19 and 24 it is brought over and above the first Vacuum-box 16 in front of the first of the series of pr'esser-rollers 11, where the fluid yet remaining is subjected to the suction exerted by the action of the vacuum-box and is drawn through the meshes of the carrier-apron 4 into the vacuum-box, and the fluid thus extracted is forced by a suitable pump L through a pipe 17 and is thrown from the openings 18 in a series of jets against the returning endless carrier-apron 4 to free its meshes of any material or pulp that may have been forced therein by the action of the presser-rollers 11. 6o

In belt-and-roller presses, heretofore invented there has been a tendency to an accumulation of material or slush before the presser-rollers; but by means of the action of the devices just described I aim to overcome terial or pulp, and by means of the construction of the machine as herein described, I aim to overcome this tendency. As the material or pulp is passed along and is subjected to the action of the presser-rollers 11 and vacuum-boxes 16, placed in front of each set of presser-rollers 11, the fluid contained therein is effectually pressed and extracted therefrom. It will be understood that, if necessary, or desirable more presser-rollers and vacuum-boxes may be added than shown in the drawings and the machine may be correrespondingly lengthened.

Fig. 5 represents a modification of my improved press.

As shown, instead of having the endless carrienapron 4 extending the entire length of the machine I mount it as shown, and it is simply used in carrying the pulp or material through the presser-rollers.

53 designates an auxiliary endless carrierapron, made of non-corrosive woven wire and mounted on the carrier-rollers 54 and designed to carry the pulp or material from beneath the grinding-cylinder and over the series of rollers 19 and beneath the series of rollers 24 and endless apron 25, carried thereby.

It will be seen that the series of rollers 24 are mounted in a similar manner to thathereinbefore described; but instead of the endless apron 25 passing around and receiving its motion from the first upper presser-roller it passes around and receives its motion from a carrier-roller 55, mounted on a shaft andherein before described and designed to assist the series of rollers 19 and 24 in hastening the flow or percolation of the fluid through the endless carrier-apron 53.

57 designates an elevatorbox provided near its lower end with a pivoted box 58 to receive the material to be ground from below and carry it to the feed-hopper 59, where it is fed to the grinding-cylinder below by means of the feed-cylinder hereinbefore mentioned. The elevator-belt receives its motion from a shaft 60 at its upper end, provided with a pulley and belting communicating with a pulley mounted on one end of the shaft of the feedcylinder. (Not shown in drawings.)

I do not desire to limit myself to the exact details of construction and form and proportion of parts herein shown and described, as I am aware that many changes therein can be made without departing from the principles or sacrificing any of the advantages of this invention.
